Huawei has developed an embedded optical time domain reflectometer (eOTDR) SFP transceiver with the largest split ratio in the industry of up to 1:64.
The Chinese telecom network vendor said its new SFP eOTDR transceiver offers cost-effective fiber maintenance by embedding OTDR functionality into an optical line terminal (OLT) PON optical module and operating at the same wavelength as user data.
Huawei said a standardized SFP eOTDR transceiver can be deployed on FTTx for troubleshooting. This approach does not require engineering reconstruction such as fiber connection changes or adaptation of optical network terminals (ONTs).
In addition, Huawei’s SFP eOTDR transceiver achieves a split ratio of 1:64 and covers mainstream FTTH scenarios, moving eOTDR technology another stage closer to large-scale commercial deployment.
“With the new SFP eOTDR transceiver, Huawei leads the industry in technology innovations by solving key issues such as reusing data wavelength to carry test signal, SNR improvement and optical module miniaturization. This will be a key milestone for future commercialization of eOTDR,” said Frank Effenberger, Huawei’s chief expert on access networks.
